This is a 14BCX300-05-1 Double-Convex Lens, sourced from Standa, a renowned vendor in the optical industry. The lens is spherical in shape, specifically a Convex-Convex lens, and has a circular base shape. It is designed with a diameter of 12.7 mm and a center thickness of 2 mm, while the edge thickness is 1.9 mm.
The lens has an effective focal length (EFL) of 300 mm, making it suitable for applications that require long focal lengths. The first radius of curvature (R1) is 310.88 mm, and the second radius of curvature (R2) is -310.88 mm, indicating a symmetrical design. The lens does not have any inner or outer radius, suggesting a uniform curvature throughout.
The lens is made of n-bk7 Schott material, a popular choice in the optical industry due to its excellent optical properties. It is designed to work with a wavelength of 546 nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens is currently in stock and available for immediate use. For more information, you can refer to the vendor's website at http://www.standaphotonics.com/lenses/double-convex-lenses.php.
